ISOPROBE® Elerostatic VoltmeterThe Model 279 ISOPROBE® Elerostatic Voltmeter measur surface potential in the range of &plun;3000 volts without containg the measured surface It featur high-accuracy (0.1%), drift-free measurements that are almost fully independent of probe-to-surface separation. Its low-profile dign is optimized for rack mounting of multiple 279's in a minimum space.
Side- and end-viewing prob accommodate various mounting requirements. Specialty high-rolution prob allow the 244A to rolve spot diameters as all as 1 mm. Prob include air purge capability to prevent ingrs of particulate.
• Elerophotographic measurements• Radiation effe studi• Eleret rearch• Eleric field studi• Procs monitoring and control• Integrated circuit manufauring and handling A. Applications:
Model 279 ISOPROBE® ELEROSTATIC VOLTMETER tak advantage of Monroe’s years of experience in
dign of reliable instruments for N-CONTAING measurement of elerostatic potential combined with
modern semiconduor techlogy. A full sperum of proven-dign interchangeable prob expos broad new
areas for exploratory rearch as well as providing a precision instrument for routine applications in elerostatic
measurements. Some tical and potential applications include:
?? Elerophotographic and xerographic measurements
?? IC manufauring and handling
?? Materials evaluation
?? Eleret rearch
?? Static elerification, eleric field studi
?? Procs monitoring and control
B. Featur:
?? Low profile half rack size for multi-channel applications
?? Full complement of interchangeable prob
?? Seleable recorder output range
?? LED meter with “blackout switch” for darkroom applications
